London's hidden museums and libraries

If you’re not fazed by the skeletons of a walrus, a baboon and a giant iguanadon that face the entrance, you’ll find many a fascinating animal specimen here (quite a lot of them preserved in glass jars, and plenty of skeletons). Part of University College London, it might at first appear chaotically cluttered, but specimens are carefully categorised into evolutionary groups. Watch out for the dodo whose bones are stored in a box and laid out in specially cutout padding.
